* bsps: Move startup files to bspsSebastian Huber2018-04-209-897/+0
| | | | | | | | Adjust build support files to new directory layout. This patch is a part of the BSP source reorganization. Update #3285.
* Remove make preinstallChris Johns2018-01-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
* pc386: Simplify bsp_specsJoel Sherrill2017-12-191-1/+2
| | | | | | | | If this has any issues, check that the change in linking the 16-bit startup code in Makefile.am generates the same code. This was odd code and didn't need the RTEMS linkcmds anyway. Updates #3520.
* pc386/.../bspreset.c: Readd proper reset code.Joel Sherrill2017-10-081-2/+2
| | | | | | | The removal of the Edison code removed the wrong part of the conditional. Closes #3172.
* Remove Edison BSP.Joel Sherrill2017-07-284-23/+1
| | | | | | Intel has obsoleted this hardware and the BSP was never completed. closes #3086.
* i386: Support thread-local storage (TLS)Sebastian Huber2017-06-121-3/+7
| | | | Update #2468.
* i386/pc386: Add support for the gdb stub to use available console drivers.Chris Johns2016-05-112-8/+23
| | | | | | | | | | | Move the gdb stub from the i386 UART code to use the libchip drivers. Use any ports discovered during the probes. Add gdb control to the boot command line. Change the device naming to the full device path, not a partial path. For example /dev/com1.
* pc386: Do not include rtems/pci.h from bsp.h. Add bsp/bspimpl.hJoel Sherrill2016-03-151-0/+1
| | | | Start to migrate private symbols to bsp/bspimpl.h.

* pc386: Improve boot command arguments for console/printk device selectionJoel Sherrill2016-03-101-0/+9
| | | | | | | | This patch adds the "--printk=" boot command line argument to specify the printk() device. It also enhances the "--console=" boot command line argument to match any device configured in the console device table. The arguments are parsed as early as possible so they take effect early. Currently, this is immediately after PCI initialization.
* Add shared PCI support and enhance pc386 to support non-legacy PCI ↵Joel Sherrill2016-03-101-5/+24
| | | | | | | | | | | | | | | configuration space This patch fundamentally results from enhancements to the pc386 BSP to support systems which do **NOT** have the legacy PCI BIOS. The patch adds support for detecting when legacy PCI BIOS is not present and then using IO space to access to PCI Configuration Space. This resulted in dynamically selected between two implementations of PCI and refactoring out the shared methods. This patch adds shared implementations of pci_bus_count() and pci_find_device(). Subsequent patches will remove implementations of these methods in other BSPs where possible.

* bsps: Call bsp_work_area_initialize() earlySebastian Huber2015-12-102-8/+10
| | | | | | | | Call bsp_work_area_initialize() before bsp_start(). This allows bsp_start() to use malloc() etc. which is beneficial for systems with a plug-and-play hardware enumeration. Update #2408.

* pc386: Add Edison base supportJoel Sherrill2015-01-044-9/+38
| | | | | | | | | The current support for the Edison supports a single polled UART for input and output plus a simulated clock tick. The activities forward for supporting the Edison have been posted on the RTEMS mailing lists and at: http://rtemsramblings.blogspot.com/2014/12/intel-edison-and-rtems-road-forward.html
* pc386: Add BSP_ENABLE_IDE BSP optionJoel Sherrill2015-01-041-0/+2
| | | | | | This allows the IDE support to be completely disabled. It is needed to prevent hangs on some hardware. In particular, the Intel Edison where it is not present.

* score: Work area initialization API changeSebastian Huber2012-10-251-26/+6
| | | | | | | | | | | | The work areas (RTEMS work space and C program heap) will be initialized now in a separate step and are no longer part of rtems_initialize_data_structures(). Initialization is performed with tables of Heap_Area entries. This allows usage of scattered memory areas present on various small scale micro-controllers. The sbrk() support API changes also. The bsp_sbrk_init() must now deal with a minimum size for the first memory chunk to take the configured work space size into account.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-113-6/+0
